MST Performance BMW M2 Competition/M3/M4 S55 3.0T Air Intake Kit

MST Performance Air Intake Kit – BMW M2 Competition, M3 & M4 (S55 3.0T)

If you want more from your BMW M2 Competition, M3, or M4, improving how your engine breathes is one of the most straightforward upgrades you can make. This air intake kit from MST Performance replaces the factory airbox with a freer-flowing setup designed to get colder, denser air into your turbocharged engine more efficiently.

The result is sharper throttle response, a more satisfying induction sound, and measurable power gains – without any complicated modifications.

What Does It Do?

The standard airbox fitted to the S55 engine is designed with cost and noise regulations in mind, which means it restricts airflow to some degree. This MST Performance kit removes that restriction, allowing your turbos (the S55 uses twin turbos to force air into the engine) to pull in a greater volume of cooler air. Cooler, denser air means a better fuel-air mix, which translates to more power and better throttle feel.

Dyno testing – controlled testing on a rolling road – has shown gains of up to 12-14bhp on the S55 engine. Results will vary depending on your vehicle’s specification and current state of tune, but gains are realistic and consistent whether your car is standard or already running an engine remap.

What’s Included?

• Black powder-coated heat shield – helps keep warm underbonnet air away from the filter
• Black powder-coated inlet pipe – directs air cleanly towards the turbos
• Red pleated dry air filter – easy to clean and maintain, no oiling required
• Silicone joiner – connects components with a secure, flexible seal
• Full fitting hardware and step-by-step instructions

Why MST Performance?

MST Performance are a well-regarded name in the intake kit market, known for producing well-engineered kits that use quality materials and fit accurately. The powder-coated finish on the heat shield and inlet pipe gives a tidy, purposeful look under the bonnet – a step up from basic intake kits that use plain aluminium or plastic components.

The dry pleated filter is a practical choice for everyday use. Unlike oiled filters, it won’t risk contaminating your mass airflow sensor (the sensor that measures how much air enters the engine) and is simple to clean when servicing.

Please confirm fitment for your specific vehicle before purchasing. Use the vehicle lookup tool on this site, or check the Vehicle Fitment tab for full compatibility details. This kit is designed for BMW M2 Competition, M3, and M4 models fitted with the S55 3.0T engine – but build year and specification can affect compatibility.
